Bringing food to work is not only healthy, but also saves the pain of queuing. Nutrition experts tell us that it is necessary to choose the dishes in the lunch box. Some foods that are not suitable for dinner are not good for health, but will cause food poisoning. Today, I will give you a list of foods that are not suitable for bringing food to work. I hope you will know how to eat and go to work after reading it. It is not advisable to bring fried and pickled food to work. Some fried, salted or overnight foods can contain carcinogens. After the damaged and destroyed gastric mucosa comes into contact with these substances, it is likely to cause lesions and lead to gastric cancer. For example, if many people don't bring lunch boxes to eat on time, or if the lunch boxes go bad after being heated again, it will bring damage and destruction to the gastric mucosa, which may lead to gastric ulcer, atrophic gastritis and even gastric cancer. It is not suitable to bring green leafy vegetables to work, such as lettuce, spinach and pea tips. Due to the enrichment of various fertilizers and pesticides used in the growth process, the nitrate content in these green leafy vegetables is high. Nitrate is one of carcinogens. You can choose to cook the food you have eaten and take it out, and put the rest in a closed and clean lunch box immediately. If you don't feel hot, you can put it in the refrigerator and eat it next time. It is not advisable to bring bean sprouts, tofu, yuba, bean skin and other bean products to work. Bean products have high protein content, delicious taste and rich nutrition, so you should eat more at ordinary times. However, rice is very perishable. Any higher temperature will turn sour. Doctors and nutrition experts suggest that in hot summer, don't bring beans and vegetables for lunch. Because they are easy to deteriorate at high temperature, if you eat them without knowing it, you will suffer. There are many people with stomachache in summer, because the temperature is high, bacteria are easy to multiply and food is easy to deteriorate. If you eat unclean food, you will hurt yourself. Of course, if you can ensure that the food is kept in the refrigerator at home, it won't be a long journey. You can still take it with you when you get to the company and put it in the refrigerator immediately. It is not recommended to bring cold salad to eat at work. The key is not to eat cold salad overnight. Cold salad is polluted during processing. Even if it is refrigerated, it is likely to deteriorate after one night. It is not advisable to put the cold salad overnight into the lunch box. In particular, it is not suitable to bring food with high oil content. It is not advisable to bring fish and seafood to work. On the one hand, fish and seafood can easily produce protein degradation products overnight, which will damage liver and kidney functions. On the other hand, it is difficult for fish and seafood heated by microwave oven to maintain their original color and flavor, which will also affect their appetite from the appearance. It is not advisable to bring green leafy vegetables. Green leafy vegetables contain different amounts of nitrate. If heated or stored in the microwave oven for too long, vegetables will turn yellow and taste bad, and nitrate will be reduced to toxic nitrite by bacteria, which will cause cancer. It is not advisable to bring overnight eggs to work. Whether eggs can be eaten overnight depends not only on whether they are heated, but also on whether they are cooked for the first time. Only after the eggs are cooked for the first time can they be cooked overnight. The same is true of tea eggs. Maybe you don't know that tea eggs are cooked twice. Boil it for the first time, crush it for the second time, and add tea and other auxiliary materials, so the tea is cooked.
